Hi All,
I have a seagate barracuda 7200.11 issue. The drive doesn't spin and hasn't been dropped. Opened in a clean chamber and the spindle moves freely. Platters seem undamaged, no remenants on the air filters through microscope and the heads are on the platter due to no parking ramp.
I suspect PCB damage, probably more to the fact the drive is completely dead. I've checked TVS diodes and they produce fine results. No visible damage, even through microscope, so is it a possibility that the motor controller has died?
Drive specific information is stored in the ROM, but the firmware is still on the platters i believe, when attempting to hook it up to HD Doctor, not working due to not spinning, mind i'm checking once more tomorrow.
Now the interesting bit. I was looking through some spares we have, and i've found a PCB with same matching codes but on a bigger model.
I have ST3750630AS | PCB code is: UJAJ-6 100466824 | PCB Sticker is: 100468979
Donor ST31000340AS | PCB Code is: UJAJ-6 100466824 | PCB Sticker is: 100468979
If i attempt to do a ROM transfer would that work even though the Donor board is specific to a larger model? If it is possible is the ROM chip no.1 or no.2?

Thats why i'm unsure, i read contradicatory things online that say it doesn't matter about that as long as you have a PCB match by sticker code, but of course i would like confirmation.
Appreciate the feedback,
Kind Regards
Chris
